10. At the end of the Sun’s life it will use up the hydrogen and helium in its core and become a white dwarf. The Sun’s mass is 2.0 × 1030 kg, its radius is 7.0 × 105 km, and it has a rotational period of approximately 28 days. If the Sun should collapse into a white dwarf of radius 3.5 × 103 km, what would its period be if no mass were ejected and a sphere of uniform density...
PartA Constants Suppose a star the size of our Sun, but with mass 9.0 times as great, were rotating at a speed of 1.0 revolution every 10 days. If it were to undergo gravitational collapse to a neutron star of radius 12 km, losing three-quarters of its mass in the process, what would its rotation speed be? Assume also that the thrown-off mass carries off either no angular momentum Express your answer using two significant figures. A2c rev/s Part B...
Question 16 Exoplanets A and B are observed to orbit Star X in circular orbits at distances 1.1 AU and 10.2 AU from Star X, respectively ( 1 AU = 1.5 x 1011 m) . The orbital period of Exoplanet A is 244 days. What is the mass of Star X? (1 day = 86400 s.) Group of answer choices 2.5 x 1030 kg 4.0 x 1030 kg 5.0 x 1030 kg 3.5 x 1030 kg 1.0 x 1030 kg...
2) Densities We discussed White Dwarfs and Neutron stars, very dense objects compared to stars like our sun. On the other hand, we also discussed Red Giants which are much less dense than our sun. To realize just how dense, please compute the average densities (in kg/m) for a) the sun (Rsun=7 x 10 km, Msun= 2 x 1030 kg) b) when the sun becomes a red giant (R= 1AU, M=Msun). By what factor is a Red Giant less dense...
